Title: Improved means for measuring angular velocities and displacements
IPC: G01C19/56
Filed: 1949-04-29
Abstract: 685,369. Turn-sensitive devices employing vibrating masses. VICKERS-ARMSTRONGS, Ltd., and JEFFREE, H. April 28, 1950 [April 29, 1949], No. 11538/49. Class 97 (iii). [Also in Group XXXVIII] An instrument for determining the angular displacement of, e.g., an aircraft, or its rate of pitch or yaw, comprises a reed 19 fixed at one end in compression against a piezocrystal in a housing 20 and supported between two diaphragms 13, 14, so that the free end, which is provided with mass balancing screws 191, may vibrate between three or more equi-angularly spaced electrodes 22-25, each of which is joined to a lead 26 for external connection. To detect roll, one pair of electrodes 22, 24 is charged to cause the reed 19 to vibrate in that plane, so that angular displacement of the instrument leaves the reed vibrating in the same plane in space, and signals are generated in the opposite pair of electrodes 23, 25, which may be detected and measured. To detect pitch or yaw, the free end of reed 19 is given a circular motion by a cyclic charge on the electrodes 22-25, so that a rotation about an axis perpendicular to the reed produces an end load on the piezo-electric crystal at 20, which can be measured. The electrodes 22-25 may alternatively be coils or piezo-electric crystals. Reference has been directed by the Comptroller to Specifications 601,051 and 611,021.

Title: Improvements in Means for Regulating Internal-combustion Engines.
Inventor: RATEAU AUGUSTE
IPC: F02B37/18
Filed: 1917-08-14
Abstract: 128,625. Rateau, A. Dec. 7, 1916, [Convention date]. Regulating.-Engines for aircraft are charged with air under pressure by a blower B actuated by a turbine D driven by exhaust gases from an internal-combustion engine A. The air is delivered to a carburettor C, and in the event of the blower being out of action, or delivering less than an adequate charge, supplementary air is drawn in through an automatic valve 8. The blower may be put out of action wholly or in part, by bypassing the exhaust gases through a valve 9 leading to the atmosphere. The valve may be controlled by hand, or automatically by a flexible diaphragm 20 open on one side to the atmosphere and on the other side acted upon by air at normal atmospheric pressure. The pipes leading to the turbine and from the blower have cooling-fins 11, 15 respectively. To prevent overheating of the turbine, cooling-air is supplied through a pipe 6 leading from the discharge pipe 4 of the blower. In a gas-engine, the gas is supplied by a separate blower.

Abstract: 1291544 Embossing PANDEL Inc 27 April 1971 [27 April 1970] 11695/71 Heading B6J To provide a variation in the embossed pattern produced by an embossing surface on the surface of a thermoplastic resin sheet material, a layer of a material having a modulus of elasticity different from that of the resin is interposed, under tension, between the embossing surface and the resin sheet. By controlling the tension of the layer different embossed effects are obtained on the resin sheet while using the same embossing surface. The embossing surface may be the surface of a roller. The layer may be drawn from a braked roll or may be in the form of an endless belt. The layer may be composed of synthetic resin (examples are given). The thermoplastics resin sheet may be composed of vinyl resin, olefinic resin, acrylic resin or urethane resin, and may contain a blowing agent which is activated subsequent to the embossing step.

Filed: 1973-03-12
Abstract: 1364823 Pulse detecting circuits INTERNATIONAL BUSINESS MACHINES CORP 12 March 1973 [29 March 1972] 11710/73 Heading H3T Data signals are detected by applying the signal to a gate 250 via two parallel paths, the first 240 producing an output in response to the peak of the signal and the second 220 producing an output when the signal exceeds a threshold value, the latter being lowered upon response to a peak. Separate circuits may respond to positive and negative polarity input signals and control set and reset inputs of a bi-stable circuit. The amplifier 210 comprises a first stage AQ1-3 (Fig. 4), a second stage AQ4-6 and parallel output stages AQ8 and AQ7 and 9 providing erect and inverted signals respectively. The output transistor AQ6 of the second stage is in series with the transistor AQ4 of the first stage and provides negative feedback via resistor AR14. Feedback to the emitter of AQ2 is provided by an adjustable resistor AR28. The thresholders, Fig. 5, comprise an emitter coupled pair having the threshold level determined by the bias on transistor TQ2. When the signal level is positive TQ2 and 3 are off and the bias is determined by network TR4 and TR6-8. When the signal is negative TQ3 conducts and reduces the threshold level. The peak detector (Fig. 6) comprises a unity gain feedback amplifier PQ1, 2, 3 feeding a differentiating capacitor PC2. When a signal passes through its peak the sign of its output reverses. This reverses the direction of current through feedback diodes PD7 and 8 and produces a voltage step and thus pulses of opposite sign at outputs 241 and 243 respectively, the length of the pulses being controlled by the time constant of capacitors PC5 and 6. The gating circuit (Fig. 7, not shown) comprises a diode gate followed by a transistor amplifier.
